Olfactory-auditory sensory integration in the olfactory tubercle. Bar graphs of average stimulus evoked responses across 17 units in response to tone (left), odor (middle, see methods for odor) and simultaneous tone and odor presentations (right column).hus, both accessory and main olfactory systems converge in the olfactory tubercleâpresenting this structure as a âmixedâ olfactory cortex (Martinez-Marcos, 2009). These anatomical points highlight the likely role of the tubercle in the processing of odors.
Precancerous condition. A precancerous condition or premalignant condition, sometimes called a potentially precancerous condition or potentially premalignant condition, is a state of disordered morphology of cells that is associated with an increased risk of cancer. If left untreated, these conditions may lead to cancer.
The presence of certain cancers can be confirmed by the specific proteins being shed into the blood. These proteins are the tumor markers. Carcinoembryonic antigen (CEA) is the protein linked to colorectal cancers. Every one of us has a little CEA in our blood. The presence of this protein in the blood alone does not mean you have colon cancer. The CEA blood test cannot be used to diagnose cancer, only to track cancer after a diagnosis.
